{{Short description|Networking API for MS-DOS}}

'''PC/TCP Packet Driver''' is an [[Application programming interface|API]] created in 1986 by [[FTP Software]] for [[network card]]s under [[x86]] [[Disk Operating System|DOS]] like [[MS-DOS]], [[DR-DOS]], [[FreeDOS]], etc. It uses an [[INT (x86 instruction)|x86 interrupt number]] (INT) between {{nowrap|60h .. 80h.}} The exact interrupt number is detected at runtime, most commonly 60h.

'''PC/TCP Packet Driver''' is a networking [[Application programming interface|API]] for [[MS-DOS]], [[PC DOS]], and later [[x86]] [[Disk Operating System|DOS]] implementations such as [[DR-DOS]], [[FreeDOS]], etc. It implements the lowest levels of a [[TCP/IP]] stack, where the remainder is typically implemented either by [[terminate-and-stay-resident]] [[device driver|drivers]] or as a [[software library|library]] linked into an application program. It was invented in 1983 at [[MIT]]'s Lab for Computer Science (CSR/CSC group under [[Jerry Saltzer]] and [[David D. Clark]]), and was commercialized in 1986 by [[FTP Software]].

AnA applicationpacket driver uses thean [[INT (x86 instruction)|x86 interrupt number]] vectors(INT) between {{nowrap|60h .. 80h.}} The number used is detected at runtime, it is most commonly 60h but may be changed to avoid application programs which use fixed interrupts for internal communications. The interrupt vector is used as a pointer (4-bytes [[Endianness|little endian]]) to the address of a possible [[interrupt handler]]. If the null-terminated [[ASCII]] text [[string (computer science)|string]] "''PKT DRVR''" is found within the first 12-bytes -- more specifically in bytes 3 through 11 -- immediately following the entry point.

Packet drivers can implement many different network interfaces, including [[Ethernet]], [[Token ringRing]], [[RS-232]], [[ARCNET|Arcnet]], and [[X.25]].<ref name="crpkt">{{cite web |title=PC/TCP Packet Driver Specification |url=http://wwwcrynwr.com/packet_driver.html |archive-date=November 27, 2022 |archive-url=https://web.archive.org/web/20221127060523/http://crynwr.com/packet_driver.html}} 090430 crynwr.com</ref>
